I've heard phrases like just in time, just at the right time...
but if there are no other hints, are 'on time' more or less the same as 'in time'?
thanks
on time = happening or done at the particular moment that it was expected to happen or be done.
The bus arrived right on time.
in time = early enough
I got home just in time - it's starting to rain.
